CUTTER DECK ADJUSTMENTS
Due to the many conditions that exist, it is
difficult to suggest a setting that will work for every
lawn. There are, however, two adjustments that
should be made on the cutter deck: pitch and
height.
PITCH is the angle of the blades (comparing
front to rear). A 1/4" downward pitch (front of
deck down) is recommended for better cutting
performance.
HEIGHT is the nominal distance that the
blade is off the ground. This measurement is made
with the blades pointed side to side and distance is
measured between cutting tip and ground.
Adjusting the blade height can be done by
moving any number of the five smaller spacers on
the blade mounting bolts to the top of the spindle
shaft or below the spindle shaft. All blades should
be positioned equally (see Spindle Illustration, p. 8).

breakage, see your authorized Scag service dealer for belt
adjustment.

The Scag mower, including any defectivepart must be returned to anAuthorized Scag Service Dealer within the warranty period.
The expense of delivering the mower to the dealer for warranty work and the expense of returning it to the owner after repair
